The method of the invention is to install a respective photo coupler to the input port as well as the output port of each system terminal device and then to connect the system devices of the network system in series, so as to isolate the electric signal of one system device from another and to detect if the system terminal device is at the terminal end of the network system, and to connect the input port as well as the output port of each system terminal device to respective terminal resistance through a respective switch, permitting each switch to receive the control signal from the respective photo coupler so that the actual location of the system terminal device is shown and the necessary terminal resistance will be automatically installed when necessary.
